The paperwork-based, process-oriented, traditional waterfall model

Traditionally in the early 2000s, in the waterfall model
, QA was always seen as a subsequent phase to development, often referred to playfully, as the dishwashing stage of the SDLC.
This course of haemostatic events has been explained by developing theories to elucidate all interactions between platelets, coagulation factors via the waterfall model
, cofactors without enzymatic activity, antithrombotic mechanisms, and so on.
Some of these were the Iterative model, Waterfall model
, Sashimi model, Spiral model, Fish Bone or Ishikawa Diagram, and Prototyping.
Although many models have been presented at the beginning of the waterfall model
.Each phase of the SDLC (Software Development Life Cycle) is vulnerable to the different kinds of risk factors.
For the purpose of automation of assessment of classification type answers, a classification models namely waterfall model

Whether it is a system admin learning to build new tools, or developers using a model other than the Waterfall model
, DevOps firmly places your organisation in the growth zone.
It has its roots in the world of software development, where the software project management community got weary with the inefficiencies and theocracy of the Waterfall Model
, which presupposes a fixed, unchanging scope, monolithic development and, finally, one-shot user acceptance testing, where it's inevitable that there be rejects, negotiations, leading to a badly compromised product being shipped out into the marketplace.
